San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
What Are Some Rat Diseases That Can Affect Humans?
One of the biggest concerns of countries and cities suffering from plagues of rats is the many diseases they cause. Many lethal diseases have been caused by these pesky rodents and more and more places are being exposed to rat diseases.
Rats are carriers of numerous pathogenic microorganisms such as viruses, bacteria, parasites, and other types of infectious agents, which can be transmitted through different parts and secretions of the rat; its tissue, saliva, urine, and feces.
How Can Rats Infect Humans?
Rats can transmit diseases through their skin; contagious infections that could be fatal in the skin of the affected person.
Through their saliva, rats can transmit a great number of viruses, bacteria, and infections, both internally and externally. That is why it is essential to go to a doctor if a rat bites you.
Rat urine and feces are among the most dangerous carriers of infection. They carry the most viruses and diseases which, if not treated in time, could have serious consequences for the health of the infected person.
The importance of being alert to the first sign of rats on your property is critical to your family's health. Not only your children and family but also your pet, as they could be exposed to even more infections and diseases that are deadly if not treated in time.
Some of the symptoms that could appear after a rat bite are:- Chills
- Fever
- Dizziness
- Muscular ache
- Breathing difficulty
Some of these symptoms are just a preview of a serious illness caused by constant exposure to rats. Some of these diseases include meningitis, gastrointestinal and respiratory problems, bubonic plague, toxoplasmosis, salmonellosis, internal parasites, among others.
Keeping your family out of harm's way should be a priority. When you first see a rat, you should do something about it; either hire a pest exterminator or set traps throughout the house yourself.
